Measurements of top-quark properties at the LHC

Measurements of several top-quark properties are presented, obtained from the ATLAS and CMS data collected in 2011 and 2012 at centre-of-mass energies of 7 and 8 TeV. The results include measurements of the top pair charge asymmetry, the top quark polarization in pair production and single top production, the W helicity in top decays. Results of spin correlation in topquark pairs are presented and interpreted in terms of the SM predicted values. The results are compared with predictions from the standard model as well as new physics models. The cross section of ttbar events produced in association with a W, Z boson or a photon is also presented.
